LONDON -- Apparently Cristiano Ronaldo doesn't know his own strength.

Well, either that or his teammate Adrien Silva is a really, really good actor.

In the four-second clip, Ronaldo casually punches Silva on the leg -- and probably gets a stronger reaction than he was expecting.

To be fair, Silva does look as though he's laughing right at the end of that clip (so it's always possible he was having Ronaldo on).

Either way, it's still a beautiful moment.
